We backup first thing in the morning, by the staffer who arrives first, or on Friday when she is absent I back up from home, late Thursday night.
Bert if you want the dropped connection, use Linksys and get about 4 laptops on at once. Then get several cell phones on in the area. I consistently loose the connection when I unplug the lap top, move to the next room all at the same moment as it is trying to open the next chart, when it was idle for a minute or so.
We are testing some 'thin clients' in two of our exam rooms to allow us to be hard wired so we can phase linksys out.
